Google Increases Max Gmail Message Size
Over the weekend, Google increased the maximum size of Gmail messages with attachments to 25MB. (click here to learn more)
This means that you can attach files of 22-25MB to your message, provided the total size of the message does not exceed 25MB.
The challenge, of course, is will the recipient’s email system let the message in. Many corporate email systems put limits on message sizes in the 2GB to 5GB range.
